Check Digit Verification of cas no

The CAS Registry Mumber 131122-76-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,1,2 and 2 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 131122-76:
(8*1)+(7*3)+(6*1)+(5*1)+(4*2)+(3*2)+(2*7)+(1*6)=74
74 % 10 = 4
So 131122-76-4 is a valid CAS Registry Number.

DIASTEREO- AND ENANTIOSELECTIVE SYNTHESIS OF 1,2-DIOLS BY VANADIUM(II) PROMOTED PINACOL CROSS COUPLING

Annunziata, Rita,Cinquini, Mauro,Cozzi, Franco,Giaroni, Paola,Benaglia, Maurizio

, p. 5737 - 5758 (2007/10/02)

The V(II) promoted pinacol cross coupling of a chiral aromatic aldehyde with achiral aliphatic aldehydes occurs to afford syn diols in up to 91:9 diastereoisomeric ratio and up to 84percent enantiomeric excess.The pinacol coupling of (S)-lactaldehyde and (R)-glyceraldehyde derivatives has also been studied and matching and mis-matching pairs have been identified.The stereochemistry of the products was established by correlation.The sense and degree of stereoselection is discussed.
